Program to calculate PPM using MQ sensor: Thecomplete programto calculate PPM using a MQ sensor is given below. Few important lines are explained below. 在继续程序之前,我们需要输入负载电阻 (RL)、斜率 (m)、截距 (b) 和新鲜空气阻力 (Ro) 的值。获取所有这些值的过程已经解释过了,所以现在让我们...
MQ-X传感器连线图 这里我们使用Arduino控制器来做测试,Arduino内部自带10位AD采样电路,程序简单,使用非常方便。 如图所示,气体传感器属于模拟传感器,使用模拟传感器连接线将气体传感器连接到Arduino传感器扩展板的模拟口0上,由于气体传感器内部有发热器件耗电量比较大,所以建议Arduino采用外部供电。将代码编译后下载到Arduino上。
